Aqua regia gold refining tumbler
This refining system consists of a large PPl cylinder inclined to an angle of 25°, it continuously rotates by means of a special motor, with the possibility to adjust the rotation speed. The rotation forces the grains to rub against each other and consequently a rapid and effcient dissolution process is induced.
A Pyrex glass condenser is positioned externally to the tumbler with cold water circulating inside that allows for partial acid recovery and initial fume neutralization.
Another advantage is that it can work throughout the night without supervision.

Iao/br tita - titanium gold refining tumbler
The titanium refining tumbler is a new versatile, durable, and heavy-duty unit for the dissolution of precious metal alloys.
This is an innovative system that allows precious metal alloys to be refined with both aqua regia and inquartation.

Pre-refining unit for low karat gold alloys (inquartation method)
The plant of inquartation consists of a reactor by stainless steel or Pyrex glass, provided with a heating system (direct or indirect). The reaction time is comprised between 3-6 hours and the controlled addition of nitric acid helps to reduce the amount of nitrous vapors (NOx) developed.

Silver nitrate salt production unit
Silver Nitrate Salt Production process is carried out by the following steps:
A) Silver Dissolution by Nitric Acid
B) Nitrate solution Filtration
C) Concentration of the silver nitrate solution
D) Crystallization of the solution
E) Drying of the Salt
By using this method you can get a final purity of Silver Nit

Silver refining chemical plants
The refining process is chemical and is realized by a specific and rigorous procedure that uses base chemical reagents with low-pollution impact. The cylindrical reactor with agitator is appropriately designed to allow perfect hom*ogenization during the conduct of the process and ensure a complete reaction.
More information
Static glass refining plant
The aqua regia refining process is used to refine gold alloys using a combination of acids and chemical products. The aqua regia solution consists of a mixture of hydrochloric acid HCL and nitric acid HNO3.
